mechanical properties of HDPE.
mechanical properties of HDPE.
(OP)
hi ,
i am doing a structural analysis on a part made of HDPE. i am assuming it to be a lineary elastic material. then what can be the best values for youngs modulus, poissons ratio, yeild stress. etc.
thanks in advance.

thanks for ur suggestions.
i tried matweb and efunda also, but i couldnt find poissons ratio.
thanks

THis is one of the site where i got the data
http://www.cctplastics.com/hdpe.html
And these is the data given by Matweb
http://ma
THis the data from RTP Website
h
So tell me how to use this data appropritely.
and what about poissons ratio.
Thanks in advance

If the environment is room temperature with short loading time, then typical properties for HDPE are:
E = 1.05 GPa
ν = 0.35
yield stress = 25 MPa

I use 0.38 for Poisson's ratio (and have done for 30 years).
Modulus is highly variable with temperature, loading time and actual stress induced.
